I am getting some new tires and have a question and I am looking for your opinions. The stock tires are 215/75/15 tires, but I was thinking I would like a little taller sidewall so the guy at the tire store gave me a price on some 235's. I got to looking at the product sheets and for every jump of ten in aspect ratio the diameter of the tire increases 0.60 inches. The problem is when I looked at the weight of the tires from 215 to 225 to 235 the weight jumps dramatically from 225 to 235, not so from 215 to 225. I am jumping more than 2 pounds per tire going from 215 to 235, and only .6 pounds more going from 215 to 225. Any reason why I should go with the extra weight and additional height over the 225, or do you think the 225 would be a good compromise?
